Descriptions
The DM2282 is a high voltage, fully digital stepper drive developed with advanced DSP control algorithm based on the latest motion
control technology. It has achieved a unique level of system smoothness, providing optimal torque and nulls mid-range instability. Its
motor auto-identification and parameter auto-configuration feature offers quick setup to optimal modes with different motors. Compared
with traditional analog drives, DM2282 can drive a stepper motor at much lower noise, lower heating, and smoother movement. Its
unique features make DM2282 an ideal choice for high requirement applications.
Applications
Suitable for a wide range of stepper motors, from NEMA size 34 to 51. It can be used in various applications such as laser cutters, laser
markers, high precision X-Y tables, labeling machines, CNC router, etc. Its unique features make the DM2282 an ideal choice for
applications that require both low-speed smoothness and high speed performances

PUL+
I
Pulse Signal: In single pulse (pulse/direction) mode, this input represents pulse signal, each
rising or falling edge active (software configurable, see DM drives software operational
manual for the detail); In double pulse mode (software configurable), this input represents
clockwise (CW) pulse, active both at high level and low level. 4-5V when PUL-HIGH,
0-0.5V when PUL-LOW. For reliable response, pulse width should be longer than 2.5μs.
Series connect resistors for current-limiting when +12V or +24V used. The same as DIR and
ENA signal.

DIR+

Direction Signal: In single-pulse mode, this signal has low/high voltage levels, representing
two directions of motor rotation. In double-pulse mode (software configurable), this signal is
counter-clock (CCW) pulse, active both at high level and low level. For reliable motion

response, DIR signal should be ahead of PUL signal by 5μs at least. 4-5V when DIR-HIGH,
0-0.5V when DIR-LOW. Please note that rotation direction is also related to motor-driver
wiring match. Exchanging the connection of two wires for a coil to the driver will reverse
motion direction. The direction signal’s polarity is software configurable.

Enable signal: This signal is used for enabling/disabling the drive. In default, high level
(NPN control signal) for enabling the driver and low level for disabling the driver. Usually
left UNCONNECTED (ENABLED). Please note that PNP and Differential control signals
are on the contrary, namely Low level for enabling. The active level of ENA signal is
software configurable.

Fault Signal: OC output signal, active when one of the following protection is activated:
over-voltage, over current, low voltage, phase error and over-temperature. This port can sink
or source 20mA current at 24V. In default, the resistance between FAULT+ and FAULT- is
high impedance in normal operation and become low when DM2282 goes into error.

Auto-Configuration
Switch SW4 two times in two seconds will activate parameter Auto-configuration for DM2282’s current loop. That is, OFF-ON-OFF or
ON-OFF-ON. During Auto-configuration, motor parameters are identified and DM2282’s current loop parameters are calculated
automatically. The motor shaft will vibrate a little during the process of Auto-configuration which takes about 1 to 3 seconds.
